Relaxed model for the hysteresis in micromagnetism.
Proc. R. Soc. Edinburgh, Sect. A 139, Part 4, 759-773 (2009)
We study a model of ferromagnetic material with hysteresis effects. The magnetic moment behaviour is described by the nonlinear Landau-Lifshitz equation with an additional term modelling the hysteresis. This term takes the form of a maximal monotone operator acting on the time derivative of the magnetic moment. In our model, it is approximated via a relaxing heat equation. For this relaxed model we prove local existence of regular solutions.
